Objective:To explore protective action of ultramicro-powder of Rhizoma Gastrodiae on nerves in the rat of Cerebral ischemia- reperfusion injury.Methods:The local ischemia-reperfusion injury at model was established by cerebral ischemia for 2 hours and reperfusion for 24 hours.HE staining,2,3,5-triphenytetrazolium(TTC)staining,immunohistochemical methods were respectively used to investigate pathological changes of brain slices,the size of cerebral infarction and nervous cell apoptotic relative proteins Bcl-2,Bax expression after treatment with ultramicro-powder of Rhizoma Gastrodiae.Results:(1)Ultramicro-powder of Rhizoma Gastrodiae could reduce the size of cerebral infarction.When the low,middle and high dose groups were compared with the ischemia group there were significant differences(P

Glucocorticoids have remained important anti-inflammatory agents in the treatment of chronic kidney disease (CKD).However,the use of glucocorticoids can invoke or enhance insulin resistance,which is closely associated with renal injury and serves as an independent risk of the occurrence and progression of CKD.On the other hand,CKD patients may have insulin resistance,which hampers the use of glucocorticoids in these patients.

The Wnt pathway plays a crucial role in skeletal development and is indispensable for determination of OS cell lines. In recent years, experimental evidences on Wnt signaling pathway in OS cell lines and OS animal models, and that of Wnt signaling pathway as a diagnosis and prognosis marker of OS suggested that Wnt signaling pathway plays an important role in the progression, invasion and metastasis of OS. In addition, the strategy and safety evaluation to target Wnt to treat OS are underway. Exploring the significant role of Wnt signaling pathway in OS may aid in personalizing therapeutics to increase patient survival.

Objective To investigate the effect of Bcl-2 gene knockdown on apotosis , proliferation and drug sensitivity of gastric carcinoma HGC-27 cells. Methods The HGC-27 cells were divided into five groups:the untreated control group , the control siRNA group , the specific siRNA targeting Bcl-2 gene group , 5-FU treated group and the combination group (Bcl-2 siRNA and 5-FU treatment). Then flow cytometry and MTT assays were performed to detect the apoptosis and proliferation of HGC-27 cells. The cysteine protease activityand Cytochrome C release level were tested by ELISA method. Results Bcl-2 knockdown enhanced apoptosis and inhibited proliferation of HGC-27 cells. Comparedwith the 5-FU-treated group , the cell apoptosis level, activities of Caspase-3 and Caspase-9, plasma Cytochrome C were significantly increased in the combination group(P <0.01). Conclusion Bcl-2 gene knockdown induced apoptosis, inhibited cell proliferation and enhanced the drug sensitivity of 5-FU in gastric cancer cells , which might be considered as a potential therapeutic strategy forgastric carcinoma.

Serious troubles were caused by the highly heterogeneous cancer cells in clinical cancer treatment.In recent years,molecular characterization of tumors and corresponding individualized cancer management has become hotspots for cancer research.Circulating tumor cells (CTCs) are shed from primary solid tumors or metastases into the peripheral blood.CTCs could serve as liquid biopsy for patients with cancer,with non-invasive,real-time and repeatable access.Serial monitoring of the amount and molecular characteristics of CTCs in the blood samples has significant clinical value for prognostic prediction,targeted drugs choice and real-time evaluation of clinical effectiveness in individualized cancer treatment.This review summarizes current methods for the CTC isolation and detection,and discusses the perspectives of CTC analyses in real-time personalized cancer therapy.Some future research directions in this field are proposed.

Sepsis associated encephalopathy (SAE)is the most common form of encephalopathy in the pediatric intensive care units and might appear before other systemic features of sepsis.The pathogenesis of SAE is complex and not clear.SAE causes increased morbidity and mortality but has limited therapeutic options.SAE has become a hot issue in critical care medicine.

Activated protein kinase ( AMPK) , an important energy receptor , plays a very important role in regulating organ-ism and the energy metabolism of the cell .AMPK has complex relationship with survival of different types of breast cancer cells .Ac-cording to different conditions , AMPK may exist both anti or promoting effect on tumor .In this review , we summarize the relationship between AMPK and breast cancer related signal pathways , AMP and breast cancer endocrine therapy , breast cancer chemotherapy , ra-diotherapy for breast cancer , treatment of triple negative breast cancer and multi drug resistance of the relationship , we also expound some drugs related to AMPK and used in clinical setting .

The ion beam bioengineering study articles for 1994 -2003 years were retrieved, the research material and the level of the research, magazine, the ion source and the fund source were analysed and counted. The results indicate that the ion beam bioengineering of China get a fast development under the support of the nation and the local government and college. The development in the field of microbe is the fastest. in 21st century, the local government and colleges gradually enlarge the support of the ion beam bioengineering, some articles are under the support of enterprise researcher and fund. The contents of these articles mainly about application study. After analysing the data, the future of ion beam bioengineering of China was forecasted.
